Let me help you with some math and logic. If 52% of people have flown in the past year and 70% of those flights were leisure then 0.52x0.7 = 0.364 or 36.4% flew for leisure in the last year and 63.6% did not.

Presumably the 2/3 who didn't fly for vacation also didn't spend 3000 and change which is hint just what a bank told you it should cost not how much people especially poor people are actually spending. There is a massive disparity between the haves and have nots in America.

Tldr: they aren't living paycheck to paycheck because they spent 3000 they are doing so because shit is expensive. People also aren't poor because they eat too much avocado toast.
